Be it known that I, Gnoncn W.IBONHAM,i a citizen of the =United States, residingat Helena, in the coun'ty of Alfalfa and {State} ofOklahoma, have inventedanew and use- .cful TireBolting Machine, of which the fol-1f lowing is a specification.

proved nut feeder whereby all of the nuts supplied to the machine will beyfed accu-j,

,rately to the wrench employedfor screwing them onto 'the bolts.

Another object is to provide -a .WlBllCh havingan adjustable and yieldable nut rest; whereby-a nut within the wrench is freetoi iyield when subjected to pressure .without in- .juring thethreads on the tire bolt.

A ,further object is :to .providerneans forl shifting-the nut;feeding=,mechanismintoandi y seated within the lower portion of 1 the. shank out of operative position.

With the foregoing andiother objects inview which will appear as the description proceeds, the invention resides inathe. combination and arrangement of;parts;and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment ofthe,invention herein disclosedcan :be .made within the scopeof what'is claimed, withoutdeparting .from the spirit of the :lIIVG/I'Itl on.

Referring to (th figures by charact r o reference 1 designates asupportil gfilate or standard adapted to be bolted ;or 1 otherwise 1 secured to a wall orother supportingg structure, this plate being provided, at its upper p I 1' .end, with a head 2 having a boxing 3 secured to one side thereof. This boxing is preferably seated Within a recesst formed in the head and may be held in place by means ,of anarmfi extending into the head. Thisarm has a slot 6 for the reception of a 'key 7 insertible' downwardly through the head. :Obviously, by removing the key, the

boxing?) can be disengaged from thehead. v f llhe nner face of the boxing has asemicircular recess 8 registering with a corresponding recessy formedwithin the adjoining face of the head 2. These two recesses'cooperate to form a passage ,9 the upperend of which is counter bored, as indiQated at l0. Thepassage 9 is adaptedto receive'the tubular shank l1 ofa wrench head 12. This head is mounted for rota- ,tionwit-hin the counterlbore l0 and has an angular nut receiving opening 13. The

shank llext-ends below the'head 2 and the passage therein extends throughout the length ofthe shank, therebeing a bayonet slot 14: ingthe' lower end portion of the shank. A nut restis adapted to be detachably :11 and, as shown'inidetail in F 5, includes ,a tapered head 15 havinga screw threaded.

stem .16 which is .slidably mounted :within a tapered plug A spring 18 extends around the shank and bears atone end against the plug and at its other. end'against engages thej ilower end portion of theshank 16 and is contacted by the plug 17. The lug is adaptedtobe inserted into the bayonet :slot, the plug 17, I at' that time'clos'ing the lower en'd,oftheshank. When the parts are thus positioned, the head '15 ,abuts against the shoulder 22 formed at the inner end of the angular opening 13.

A-gearxQS is formedon or secured. tothe ,another gear 25-.secured :to one end of an operating shaftg26. Thisshaft is journaled .within bearings 27 formed on or secured to the-plate '1 and-Jan operating wheel 28 is secured to one end, of the shaft 26.

' and at its other end against collar 31 which is .adjustably connected to the "rod 29 by means of a set screw 32 or the like. This coll ar has an arm 33 extending therefrom and provided with a forked'terminal '34 which straddles and slidably engages a guide rib 35 extending longitudinally along the plate 1. The lower end of the rod 29 is connected, by means of a link 36, to a treadle 37 hingedly connected to the plate, 1. Itwill be apparent that the forked arm '33will prevent rod 29 from rotating and by V adjusting the collar 31 along the rod the tension of the spring 33 can be varied. Azeollar 38 is adjustably mounted upon the rod 29 at a point above collar 31 and 1 constitutes a support for the lower end of a sleeve '39 which'is. loosely mounted on the A set screw 40 extends'through nected to the lower end of sleeve'39 and is "extended laterally from rod 2980 as'to hold a wheel' inalinement with the wrench here-i 'toforefldescribed.

.- The upper .endjo'f the rod 29 iscurved downwardly as; at 42 so as to overhang the wrench 12 and a holding ehisel 43 is secured-to this overhanging portion ofthe rod. and is 'for the purpose hereinafter set forth; "It is to V be understoods that the spring 33 normally elevated above holds the chisel the'wrench'.

Guide'bolts 44 engage the head 2 and vj {tend through slots '45 formed in a slide 146 mounted on the head 2. arm 47 extends upwardly from one end portion of the slide and hasan inelinedslot 47 therein in which isi'nounted a roller 49. This roller, as shown .in Fig. 8,"is'ca'rried by a collar 50 adjustably mounted upon the; upper portion of red 29. An extension 5i;is;f rmed upon one end of the slide 46 andis secured to a 'fe'e'debox 52 jfrom which extends a trough 53'. This troughfprojects upwardlyand is l slightlyfinclined and is provided, at its up- Qper end','with a clip 54 detachably engaged 501' by an eye 55'fornied at the upper end of a guide rodi56. This rod extends longitudinally. ofthe' trough; 5 3 and its lower end A set screw'57 is preferably employed as securing the collar 50 to the rod 29. When is loosely seated within the box 52. It is tobe understood that when the roller 49 isseated within the upper end of the'slot 48, the

feed box 52' is located directly over the counter sunk portion 10,0f the passage 9.

it is desired to remove nuts fro-m tire bolts, the plug 17 is. removed from the shank 11 of the wrench and set screw 57 is tightened. Rod 29 is then pulled downwardly by means of the treadle'37 and the roller 49 will therefore travel along the inclined slot 48 andhold the bolt against rotation.

the head 2 of the machine.

cause the slide 46 to shift longitudinally, thus moving the feed box 52 from over the wrench and from under the chisel 43. While the treadle 37 is depressed, the set screw 57 is loosened and by then releasing the treadle, rod 29 can move upwardly without causing acorresponding movement of the collar 50. Slide46 and the feed box will thus remain in the position to which they were shifted by the downward movement of rod 29. After the parts have thus been set, the wheel is placed'with its hub on the arm 41 so that thewheel rim will extend over the head 2 and the wrench 12. When the treadle 37 is pressed downwardlythe wheel is lowered continuing the downward movement of the treadle 37, the chisel 43 will be brought into contact with, the outer end of the bolt and will thus bear tightly thereupon so as to While the parts are thus clamped together, the operator turns the wheel 28 and the gears 25 and 23 thus rotate the wrench so as to remove the nut from the bolt. As soon as this nut has been unscrewed it will drop through the shank 11.

hen it is desired to apply nuts to the wheel bolts, the plug 17 is replaced in the shank 1.1 and locked by turning the lug-20 into the bayonet slot 14. A series of nuts is then threaded onto the rod 56 and said rod is suspended from the clip 54, the lowermost nut engaged by the rod being in contact with The operator presses downward on the treadle 37 and while said treadle is in its lowest position tightens the set screw 57. By then releasing the treadle the spring 33' will raise rod 29 and cause the roller 49 to push against the the rim of the wheel will thus be supported'above the head 2 and with one of the bolts directly over the wrench. By pressing downwardly ontreadle 37, the slide 46 and feed box 52 will be moved away from the wrench and the wheel will be lowered, the

bolt moving into engagement with the nut in the wrench. This nut can, obviously, yield under the weight of the wheel and bolt so as not to injure the thread on the bolt. Further downward movementof the treadle 37 will bring the chisel 43 into contact with the outer end of the bolt. With the parts thus pressed together, the operator rotates wheel 28 and the wrench 12 is thus revolved and causes the nut engaged thereby to screw onto the bolt. As soon as the nut has been tightened, the parts are released, chisel 43 moving upwardly automatically to the position indicated in Fig. 1 and the wheel rising off of the head 2. Said wheel can then be turned so as to bring another bolt into position above the wrench. During the upward movement of the wheel and the chisel, the roller 49 will act upon the slotted arm 47 to shift the feed box 52back into position over the wrench whereupon another nut Wlll be deposited in the wrench. The

operation heretofore described can then be repeated. It will be apparent that by mounting the nuts on the guide .rod 56 all of them will be accurately fed to the wrench.

By adjustably connecting the arm 4C1 to the rod 29, the parts can be shifted for use in connection with wheels of difierent diameters.
